Although the infratemporal region is well defined anatomically, its complex topography has been the subject of numerous, and sometimes, opposite works. That is the reason why it appeared necessary for the authors to re-evaluate this topic using the original method of Combelles and Boyer, allowing to define three referential planes, and thereby, a tridimensional shape and the volume of this region. This study allows to conclude that the infratemporal region is a triangular prism with an horizontal main axis 47 mm long. Its anterior base has a mean area of 733 mm2. The posterior top consists of the Juvara slot and has a mean area of 490 mm2. This infratemporal prism contains another one, the pterygomandibular space, prismatic too. It widens out from coronoïd plane (93 mm2) to mandibular foramen plane (169 mm2) before ending as a narrow groove between the neck of the mandibular condyle and the interpterygoïd fascia. The volume of the pterygomandibular space is quite superior to the value usually reported in the dental literature. It is of 4.8 ml to 5.8 ml according to denture. These results point out the opportunity to accomodate more important volumes of anesthesic solutions, than the 1.8 ml usually performed, without any leak out of the infratemporal region.
尽管颞下区域在解剖学上有明确的定义，但其复杂的地形一直是众多研究的主题，有时这些研究结果甚至相互矛盾。这就是为什么作者认为有必要使用Combelles和Boyer的原始方法重新评估这个主题，该方法可以定义三个参考平面，从而确定该区域的三维形状和体积。这项研究得出的结论是，颞下区域是一个三棱柱，其水平主轴长47毫米。其前基部的平均面积为733平方毫米。后顶部由朱瓦拉槽组成，平均面积为490平方毫米。这个颞下棱柱包含另一个棱柱，即翼下颌间隙。它从冠状面（93平方毫米）向下颌孔平面（169平方毫米）逐渐变宽，最后在髁突颈部和翼间筋膜之间形成一条狭窄的沟。翼下颌间隙的体积远高于牙科文献中通常报道的值。根据义齿情况，其体积为4.8毫升至5.8毫升。这些结果表明，与通常使用的1.8毫升相比，可以容纳更多体积的麻醉溶液，而不会有任何溶液泄漏到颞下区域之外。
